- Specification of Letters Patent. Application filed October 8, 1906. Serial No. 837.892.

' Patented Febpl2, 1907.

T0 and whom zit-may concern:

Be it known that I, EDWARD A. Jomrsron, a citizenuof the United States residing at Sterling, in the county of Whiteside and State of Illinois,- have invented certain new and useful Im rovements in Hay-Loaders, of whichthe following is a specification; I

My invention relates to hay-loaders in which a toothed raki -cylinder o crates in a manner to rake the ayfrom t e ground and deliver it to elevating1 and conveying mechanism operative to de 'ver it upon the Waon. he object of my invention is to provide a hay-loader that is simple, strong, and eflicient and one that will readily adapt itself to inequalities ofthe surface over which it trages. h I dr e er'ri to t e accom an 'awings, Figure 1 i s a side elevati n of the machine with one of the carrying-wheels removed. Fig. 2 isan elevation from the same side as that shown in Fi 1. Fig. 3 is a sectional detail showing t e manner. in which the crank connection between the-reciprocating carriers and their driving shaft is secured to the latter. Fig 4 is a rear elevation of the machine, and ig. 5 representsa sectional detail of part of the raking-cylinder and its su porting and drivingmeans.

V Imilar reference-numerals designate like parts throughout the several views in the drawings. I

.l re resents the can'ylilng'wheels, and 2 a rotata le axle upon w 'c the 'wheels are mounted and connected therewith by means of the usual pawl-and-ratchet mechanism.

3 represents beari- -brackets .journaled upon opposite ends of t e axle and to which are secured draft-frame members 4, for-, wardiy and upwardly inclined carrier-framesupporting members 5, and rearwardly and upwardly inclined carrier-frame-supporting members 6. 4

The carrier-frame comprises the side members 7, having the transverse bars 8 and 9 secured totheir lower sides neantheir up-' per and lower ends, respectively, and secured to' the'transverse bars are a series of slats 10, longitudinally disposed and having interveningspaces.

11' represents a number of reciprocating rakes suspended-in two ranks from transversely-arranged bars 12 and 13 at their lower ends and 14 and 15 at their upper ends by means-of U-shaped metal brackets 16, secured to the rake-bars and partially encircli the transverse bars, one rank being suspeii ed from the bars 12 and 14 and the other from bars Band 15.

Above the side members 7, upon opposite sides of the carrier-frame, are arranged the side rails 17, having their lower ends secured to the rearwardly-inclined carrier-frame-su porting members 6, and arranged p aral el with and extending upward are secured to the side members, with spacing-blocks 18 in tervening, These side rails form a track for flanged'wheels 19, that are loosely journaled upon the transversely-arranged bars 12' and 13 and 14 and 15.' The bars and rakes connected thereto have a limited vertical freedom of movement in a manner to float upon the stream of hay passing u ward on the carrier, the movement being limited by means of the upper side rails 20, having their lower ends also secured t0 the frame members 6,

and extending upward are spaced apart from the rails 17 by means of spacing-blocks 21- Secured near the upper ends of the carrierframc-supporting memberso are brackets 22, having laterally-projecting sleeve portions 224, in which are journaled-o posits ends of a transverse shaft 23, having 8 wheels 24 secured thereto outside t e jour nal-bearings for the shaft.

ouble s rocket-- 25 represents double cranks that are se- 1 cured to the sprocketwheels 24 by means of the laterally-turned ends 26, being received.

by 0 enings in the sides of the wheels and seeach double crank are connected to t e transverse bars 13 and 14 of the se arate ranks of rakes by means of connectingars 28 and 29 as shown in Fig. 4. v I

Mounted upon the axle adjacent the carrying-wheels are drivin sprocket-Wheels 30,- that may be 'clutche from the carrying-wheels by any of the wellknown means, and 31 are s rocket-chains adaptedto transmit motion cm the driv ing sprocket-wheels to the double sprockets 24,.secured to the transverse shaft 23.

Pivotally mounted upon the outer ends of the sleeves-formin part of the brackets 22 are supplemental rackets 32, havin one arm 33 adjnstably conneetedwith the ame 9 cure -thereto by means'of a U-bolt 27, as shown in Fig. 3. The correspondin arms of with or unclutched l member 6 means of a bolt passing'therethrough andthrou centric'ally arrange h a slot in said arm, conrelative to the shaft 23,

as'shownin Fig. 3, and another arm 34, having a stud securedthereto, uppn whichis journaled a sprocket-wheel 36;

pm the inner ends, of the sleevesreferred to are pivotall mounted depending arms 37, and adjustconnected with thearms. are de ending members 38, having sleeves 39, in W ch are journaled oppositeends of a raking cylinden, shaft 40, and secured to the shit outside said sleeves, are sprocket-wheels 41, as shown in Fig, 5. Y

The member 38 is rovided with slotted openings to receive '6 e securing-bolts in a manner to permit the two members to be adjusted, to vary the distance between the rakedr 'ing shaft and the cylinder-driving shaft,

andtheir contacting surfaces are corrugated as an additional means for preventing accl- -dental-slipping0f one partrelative to the other.

I l l i l M0i)IOI11S transmitted from the rake-driving shaft to the-raking-cylinder by means of 1 he sprocket-wheels 2i engaging with sprocket-chains 42, connecting sprocketwheelsll and 36, the latter being adplistable about the axis ofthe rake-driving s aft by means of the swinging bracket 32 in a manner to. tighten the chain 42 when found necessary.

The members 38 are joined together .by

v means of the transverse bars 43 and 44, and

45 represents curved straps having their rear ends secured to the transverse bar 43 and their bod portion partially surrounding the raking-0y inder, o erative as strippers to clear the teeth of t e cylinder as they deliver the hay to the reciprocating rakes, the forward ends of the clearersprojecting above the path of the rakes, as shown in Fig. 2. i

' 46 represents a series ofguards having their lower ends encircling the axle and their or ends turned forward and resting upon frame member of the carrier- I'GGGIVGCl by sleeves 49, that are pivotally connected with the frame-supporting members 6, and .49" are springs encirchng. the

3 links above the sleeves, and 50 represents hand-wheels that are threaded upon the u er ends of the links and are operative to asust the tension of the springs in the wellards, in.

known way. The springs cause the rakingcylinder to float upon the surface of the ground andiyielding y draw its axle toward the main a e Y I It is advantageous to have the raking-cylinder supported in'the manner described, as. it more readily accommodatesitself to the var conditions of crop. If the swath is light, 1t does not i press ground; but as the resistahce to the teeth is increased the cylinder moves rearward and downward in a-manner to cause its teeth to become'more aggressive in their action. 3

The elevator at .itsdelivery end is providedwith an adjustable portion comprising heavily upon the a movable extension of the 'slatted'bottom of the carrier-frame, having .two transverse-bars 51 and 52, to which are secured slats 53. The bar 51 is connected, by means of hinges, with the upper transverse bar 8 of the carrier frame, and 54 represents brackets secured to the cross-bars 51 and 52, and 55 are links having one'end ivotally connected with the brackets and t eiropposite ends provided with hook portions 56, adapted to engage with notches 57 ,formed in locking-bars 58, secured to the side members of the carrierfiaine in a manner to secure the carrier ex: tension in any desired position of adjustment.
